Take weapons from leader of militia after fresh raids (6)
I believe the answer is:
disarm
'take weapons from' is the definition.
(I've seen this before)
'leader of militia after fresh raids' is the wordplay.
'leader of' says to take the initial letters.
'after' means one lot of letters go next to another.
'fresh' indicates an anagram (a fresh re-ordering of the letters).
The first letter of 'militia' is 'm'.
'raids' with letters rearranged gives 'disar'.
'm' after 'disar' is 'DISARM'.
(Other definitions for disarm that I've seen before include "Confiscate weapon or mollify" , "Pacify" , "Take weapons from or captivate" , "Relieve of weapons" , "Make less hostile, win over" .)
